T0 au who7n it 7nay conccrn:

Be it known that I, ABRAHAM M. SOUTE- ARD, acitizen of the UnitedStatesof America, residing atDenver, in the connty of Arapahoe and State ofColorado, have invented certain new and nsefnl Improvements in Bicycle-Pedal Bells and I do declare the following to be a full, clear, andexact description of the invention, snob as Will 'enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to improvements in bicycle-pedal bells of the classset forth in patents nnrnbered 570,944 and 584,312, dated November 10,1896, and June 8, 1897, respectively.

My object is to provide a bell or alarm device adapted to be attached toor monnted upon the pedals of bicycles or other velocipedes and whichshall be simple in construction, economicalin cost, reliable, durable,and efficiei1t in use; and to these ends the invention consists of thefeatures, arrangements, and combinations hereinafter described andclaimed, all of which Will be fnlly understood by reference to theaccompanyin g drawings, in Which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a perspective view of my improved deviceshown in connection with a bicycle pedal and crank. Fig. 2 is a sectiontaken throngh the bell meohanism on the line a: ac, Fig. 3. Fig. 3 is asection taken on the line y y, Fig. 2, looking in the direction of thearrow. Fig. 4 is a perspective view of the spring-held clapper-lever.

Similar reference characters indicate corresponding parts in the views.

The nnmeral 5 designates the crank of the bicycle, 6 the pedal-pin uponwhich the crank is screwed, and 7 the pedal-frame revolnble on the pin.

My improved device is monnted on the pedal-pin between the crank and thepedalframe and Will now be described in detail. Upon the inner extremityof the pedal-pin, adjacent to the crank, is located what I Will tenu ahub 8, having an interior collar 8, engaging a shonlder 6, framed on thepedal-pin. This hub is also provided With an either on the right or leftpedal, since in changing the ring from one pedal to the other it must beturned over, its position bein g reversed. The cam-ring is held inoperative position on the hub by a sleeve 10 surronnd ing the hub, oneextremity of this sleeve engaging the cam-rin g,while the otherextremity is' engaged by the gong 12, which holds the sleeve in place.The gong also engages the inner extremity of the hub. The gong, the hub8, the sleeve 10, and the ratchet or camring 9 are locked tightly inplace on the pedalpin by the crank 5 when the latter is screwed toposition, (sec Fig. 2,) cansing the said parts to turn with the crankand pedal-pin.

Loosely monnted on the hub 8 and engaging the enter surface of thecollar 80 is a circnlar plate or disk 13, which is held in place fromthe outside by a lock-nnt 14, screwed upon a portion 8 of the hubextending ontward from the collar 8. This nnt is adjnsted to allow thehub to turn freely in the diSk for purposes hereinafter explained. Uponthis disk is fulcrumed at 15 a lever 16, having et 111g 16 at oneextremity to which is attached a spring-arm 17, terminating in a bail orknob 18, adapted to strike the gong and sonnd the alarm, as hereinafterexplained. The opposite extremity of the lever 16 is provided with a ing160, to which is attached one extremity of a coil-spring 19, whoseopposite extremity is attached to a pin 20, fast on the disk 13. Thisspring normally holds the lever and the clapper or hammer arxn in theposition shown in Fig. 3. The lng 16 is of snfficient length to projectinto the path of the teeth or cams 9 of the ring 9. Each of these camshas one cnrved or inclined face A and a straight or vertical face B. Thedisk 13 is provided With one or more lngs or projections 13, extendingontward toward the pedal-frame and arranged to be 1eadily engaged by thefoot of the rider when he desires to sonnd the alann or ringthe bell.

It Will now be readily understood that normally or When the bell is notringing, all the parts of the improved device turn With the cran]: 5 andthe pedal-pin 6. The disk 123, however, being loose on the halo 8 Willcease to turn With the pin as soon as the foot of the rider is movedinto the path of the luge 13 When the foot holds the disk from turning,the hub and pedalpin Will continue (hein rotation in the directionindicated by the arrow in Fig. This movement of the hub, together withthe parts monnted thereon, causes the eams or teeth 9 of the ring 9 topass in succession under the lng 16 of the lever 16. As this occnrs theextremity of the lever to which the lug 16 is attached is thrown outwardtoward the peripheryof the disk 10, while the 111g is engaging the faceA of the cam, the spring being at the same time stretohed or plaoednnder tension. As soon, however, as the highest point of the cam-toothhas passed under the lu g the latter is snddenly released and instantlyretnrned to its normal position by the reooil of the spring 19, thnsthrowing the olapper-arm outward with suen force or momentnm as to causeits spring-arm to yield snfficiently to bring the hammer bal1 or head 18against the inner surface of the gong. It is evident th ere may be anydesired nnmber of the cam-teeth 9, cansing the hammer or olapper tostrike the gong as many times as may be desired for every rotation ofthe hnb and pedal-pin, since the operation just described is repeatedevery time a cam 9 engages the lng 16 of the lever.

Having thns described my invention,whac I claire is 1. In a bellpedalthe combination With the pedal-pin,of alarm mechanism monnted there onand normally turning With the pin, one part of said mechanism being faston the pin, and the other part being loosely mounted and provided withmeans fast thereon for stopping the rotation With the pin, thearrangement being snob that the shopping of the one part results in theoperation of the alarm meohanism.
